Desert Dust Bacteria’s Impact on Himalayan Health

Recently, a study revealed that pathogens transported through desert dust plumes from western India reach the Eastern Himalayas and are linked to respiratory, skin, and gastrointestinal diseases.
- About: The study was conducted by researchers from the Bose Institute, an autonomous institute under the Department of Science and Technology (DST), based on over two years of continuous monitoring of dust storms from arid regions of western India.
- It was undertaken to address the lack of understanding about how airborne microbes carried by transboundary dust affect human health in the cold, low-oxygen Himalayan environment.
- Key Findings: Powerful dust storms travel hundreds of kilometres, crossing the Indo-Gangetic Plain before settling over Himalayan hilltops. These dust plumes carry airborne bacteria, including disease-causing pathogens.
- Mechanism of Spread: Health impacts arise due to a dual process, horizontal long-range transport of desert dust, associated pathogens and vertical uplift of polluted air from Himalayan foothills. Together, these processes alter the atmospheric bacterial community over high-altitude regions.
- Significance: This first-of-its-kind quantitative study links transboundary dust transport to changes in Himalayan atmospheric microbiology and associated public health risks, offering crucial inputs for national health action plans and early warning systems aligned with the vision of Viksit Bharat @ 2047.
